Zo aZZ whom it ma tamer-n! 1.

Be it known tmt I, J0me RQUILL, a citizen of the United States ofAmerica, and a resident of. Chicago, in the county of Cook, State ofIllinois, have invented certain new and useful Improvements inPneumatic-Tire Shields, of which the following is a specification Thisinvention relates to pneumatic tire shields, in which an annular cushiontire or tread is applied to the periphery of a pneumatic tire. And thepresent improvement has for its object to provide a simple and efficientstructural formation and arrangement of the tire shield parts adapted toeffectively support the cushion portion of the shield in proper positionduring the stress of actual use, and in addition thereto provide theproper adhesion between the tire shield and the pneumatic tire and thusmaintain the parts in proper relation during the stress of actual use,all as will hereinafter more fully appear.

In the accompanying drawing: Figure 1, is a detail transverse section ofthe rim portion of a vehicle wheel, illustratingthe present invention inits application to the pneumatic cushion of said wheel. Fig. 2, is aforcing ring of the present tire shield. Similar reference numeralsindicate like parts in both views.

Referring to the drawings, 1 represents a portion of an ordinarypneumatic tire, upon the periphery of which is mounted the present tireshield.

2 is the skeleton reinforcing ring of the tire shield, and which Ting inthe present imprcfavement is formed with a central orificed we flanges4, at the respective-sides of the aforesaid central web 3, the outerportions of said flanges 4 being inturned to form overhanging lips 5 andprovide annular hold ing cavities for the cushion tire or tread Saidreinforcing ring is also formed with inwardly disposed annular sideflanges 6 of a curved form in cross-section, as shown, and whichconstitute holding skirts adapted to maintain the tire shield in properplace in the present improvement.

7 is the annular cushion tire or tread of the present tire shield,andwhich tread comprises a main central tread portion 8,

that class of view of the'skeleton rein-i 3, and outwardly extendingannular.

engagement inthe holding cavities formed in-the skeleton reinforcingring 2, bythe overhanging lips 5, as shown and as heretoforedescribed.Said tire or tread 7 also comprises an inner annular portion 10, whichforms a lining for the inner surface of the central web 3,-and for theinner surfaces of the holding skirts or flanges 6, of

the reinforcing ring 2. Said inner annular portion 10 is integrallyconnected with the main central tread portion 8 by arts 11 of thematerial of the tread or tire and filling the orifices in the centralweb 3 of the reinforcing ring 2, above described.

' The aforesaid-inner annular portion or lining 10, is preferably formedof some thickness at its mid-width, and tapering therefrom to a thinedge at its sides, and so that the metal of the outer portions of theholding skirts or flanges 6 of the reinforcing ring 2, will have closerelation to the periphery of the pneumatic tire 1, and

. assist in preventing any independent lateral movement or slip of thetire shield in relation to the pneumatic tire.

In the preferred construction of the present invention the cushion tireor tread 7 and ts parts, will be molded to the reinforcing ring 2, in asuitable mold and by means of the ordinary vulcanizing process, toattain the desired adhesion between the parts.

With the present improvement, the tire shield comprising the annulartire or tread 7 and reinforcing ring 2 are applied to the pneumatic tire1, while the same is in a deflated condition. After the tire shield isso applied, the pneumatic tire is properly inflat-ed, and when soinflated will very effectively hold the tire shield against anyindependent movement or slip, and without an other holding means thanthe enforced a hesion between the lining 10 and the periphery ofthepneumatic tire or cushion 1.

Ha'ving thus fully described my said invention what I claim as new anddesire to secure by Letters Patent, is

1. A tire shield comprising, a reinforcing ring formed with a centralorificed web,

outwardly extending annular flanges having inwardly overhanging annularlips, and inwardly disposed side flanges or skirts of a curved form incross-section, and an annular cushion tire or tread comprising a centraltread portion, side flanges on said tread portion adapted for engagementbeneath the having 'side fianges 'adapted for holding aforesaidoverhanging lips, and with an inner-annular portion or lining integrallyconnected to the main tread portion through the orifices in thmcentralorificed Web of 1 the reinforcing ring aforesaid, substantially as setforth.

2. A tire shield comprising, a reinforcing ring formed with a centralorificed Web, out- \vardly extending annular flanges having in- 1iWZ1Idly overhanglng annular lips, and in- Wardly disposed side flangesor skirts of a curved form in cross-section,-and an annular cushion tireor tread comprising-a central tread portion, side flanges on said tread15 portion adapted for engagement beneath the of January, 1914.
